BURN GUARD.

Application filed September 28, 1926-. Serial No. 138,286.

This invention has for its object a particularly simple, andeflicient burn guard for platen presses particularly presses having an upper press head provided with a hot polished ironing face, which burn guard is also especially economical in construction and easily applied to the upper pressing element of the machine and which does not embody or require any movable parts or mechanism.

The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.

Figure 1 is an elevation, partly broken away, of a pressing machine embodying my invention.

Figure 2 is an enlarged edge view of the upper pressing element or head provided with my invention.

Figure 3 is an end elevation partly in section of parts seen in Figure 2.

Figure 4 is an enlarged detail fragmentary view of parts seen in Figure 3 illustrating the joint between the spring and the band at the edge of the woven wire cloth of the burn guard.

Figure 5 is a view similar to Figure 3 of this burn guard provided with another form of fastening means.

Figure 6 is a detail view partly in section of a portion of the means for holding the woven wire cloth on the press heads 7 Figure 7 is a view similar to Figure 3 of a head provided with a fiat ironing face and with my burn guard spaced therefrom.

As will be understood by those skilled in the art, burn guardsinvolve various forms of cages, movable guards and other devices .re uirin mechanism which erates either during or preliminary to the closing of the press.

My burn guard comprises a flexible sheet as a sheet of woven metal cloth or screen of fine mesh extending across the face of the upper pressing element of the machine and normally spaced apart therefrom and means for securing said sheet to the upper pressing element and for holding it taut or under tension.

I have here shown this burn guard as applied to a conventionalplaten press of the type including cooperating pressing ele- 14 attached to a head 15 having a flat ironmovable toward and from the buck, the buck being stationary and carried by the usual frame 3, and the head 2 being also carried by a suitable yoke or lever 4 pivoted to the frame. This lever 4 is actuated in any suit able manner.

is a burn guard comprising a sheet of woven wire metal screen or cloth of fine mesh, the screen being of bronze, brass, copper, monel or other non-rustable material and rapid heat conducting metal. This sheet 5 1s normally spaced apart from the ironing face 6 and normally held in spaced apart relation thereto.

As here illustrated, the ironing face 6 of the head is formed concave, and the sheet 5 engages the head only at the edges of said face 6 so that all of the sheet 5 between said edges is spaced apart fromthe ironing face 6. The means for holding the screen. 5 spaced apart from the ironing face 6 at all times when the press head 2 is not under pressure comprises means which causes a tension to be applied to the sheet 5 at all times.

As seen in Figures 2 and 3, this means preferablyv comprises springs 7 extending transversely of the upper side of the head 2 and having their ends secured to the edges of the sheet or wire screen 5.

' As illustrated in Figures 2, 3 and 4, the screen 5 is provided with a band 8 around its edge and this band is provided with perforations 9 at intervals through which the hook-shaped ends 10 of the spring 7 extend. Obviously, the springs 7 will exert a tension on the screen 5 tending to hold it away from the ironing face of the head 2.

In the construction shown in Figures 5 and 6, the sheeting is held under a tension by utilizing the inherent resiliency therein and such tension is. relied upon to separate the screen from the ironing face of the head 2 and as illustrated, in these figures, the edge of the wire screen is doubled back upon it self forming a loop 11 extending entirely around the margin of the screen and a wire 12 is threaded through the loop and provided with means at its ends for tightening it and thus tightening and tensioning the wire screen. The tightening means is here shown as a turn buckle device 13.

In Figure 7 is illustrated this burn guard ing face 16 and owing to the resiliency of the metal of the guard bows outwardly away from the flat face 16 when stretched and secured at its margin to the head. The bowing out 'or spacing apart from the flat face 16 is also probably due to or facilitated by the shape or outline of the head which is rounding at its ends and is tapered from one end toward the other. The stretching of the screening in all directions around the edge of the head causes it to bow outwardly away from the ironing face.

The screen in any case it so attached to the head 2 that when the head is released from pressure against the buck 1, the screen falls or is pulled, either by the tension of the spring 7 or by the tension inherent within the screen, slightly away from the heated surface of the head and cools oft so rapidily that it is impossible to burn the hands of the operator by coming in contact with it over any part of the surface or edges of the head when the press is open.

The screen thus forms a heat conductor which cools rapidly when the head is released from pressure and provides a cool barrier which prevents the operators hands from coming in contact with the heater surface of the head and which also heats rapidly and applies its heat to the garment when the press is closed.

\Vhat I claim is:

A burn guard for laundry pressing machines which includes upper and lower pressing elements, one movable toward and from the other, said burn guard comprising a flexible sheet of woven wire screen of fine mesh extending over the ironing face of the upper pressing element and being spaced apart therefrom and movable toward the same when the pressing elements are in pressing position and springs extending transversely of the pressing element and having their ends secured in the margin of said sheet to draw the sheet tight and away from the face of the pressing element.

- In testimony whereof, Ihave hereunto signed my name, at Syracuse. in the county of Onondaga, and State of New York, this 3rd day of September, 1926.

GEORGE F. SIMPSON.
